Re: Boiler plumbing questions
Typical residential water heaters are in the 30- 40,000 input btu/hr range. So not much horsepower from one of those. It could be enough to keep pipes from freezing, but not much heating on a cold day.
High output tanks run up around 75,000, commercial tanks 500.000 or more.
The only ways to know for sure would be a heat load number for the space, or trial and error.

Re: New Energy Kinetics Boiler: Was Kettling, Now its a Water Hammer Issue
@Steamhead is correct. 60° A is the proper nozzle with 130 psi pump pressure.
@CTYankee Wondering if you could dm me a wider shot of the install as we have some questions regarding the plate exchanger location, and that loop circ on the wall behind the boiler.
Its possible some scale has moved around the system if you have cast iron free standing radiators. I cant see a dirt mag in your pictures. Have the tech thats doing the flush call me in tech support and we can go over the problem.

Re: Where can I add a scoop and air vent
@hot_rod @EdTheHeaterMan Thank you both for the detailed information! I'm not going to be able to get the Discal and do the work for at least a couple of weeks. I'll let you know how it goes. Best!

Re: Mixing a hot water loop with one-pipe steam
good idea, poor execution. you just take hot water out of the boiler and put it back in with some convenient tapings, the closely spaced tees thing wouldn't work. you can circulate boiler water directly in the hot water loop but you need to have the circulator below the water line and can't have auto air vents. you need a bypass to bypass a little return water in to the circulator so it is a bit cooler and doesn't cavitate. it will work better with a 3 piece circulator than a wet rotor because of the muck that tends to be in steam boiler water.
you could isolate it by using a tankless coil in the boiler. if you use a heat exchanger a shell and tube or small indirect will work better than a brazed plate hx.

Re: Low water cutoff not working after cleaning pigtail
Well if it fell apart that easily, maybe it is better to find out now rather than in January. Hard to tell exactly what is going on in the picture. Although it looks like mud accumulation at the bottom of the hole in the picture.
To me it looks like the threads are either all gone or all filled up metal from the old plug. If there is nothing left of the 3/8 inch threads maybe it can be drilled out and tapped for 1/2 inch threads. With a 3/8 inch pipe plug you will know quickly.

Re: Stupid Little Bracket
put some fiberglass or similar sleeving on it when you reterminate it. if the wires to it short it will not sense rollout
i would have used a little piece of hanger iron to make the bracket
